Render definition author/license

[hojberg]

Render meta data: author, license, and date etc of a definition

Dependent on https://github.com/unisonweb/unison/issues/2173

Design update

The default focused definition looks like so with menus next to the title and the avatars, "..." and "x" menu on the right only showing when the definition is in focus.

Authors

Interacting with the avatar group animates each avatar apart and hovering them shows a tooltip, while clicking shows a modal of all the authors (even those hidden in the summary group view)

"More" menu and License

Clicking the "..."—I'm calling this the "more" menu—shows a flyout of secondary options (dependents and history are placeholder and out of scope of this ticket)

Clicking the license option shows a modal with the license details

Looks great!
